BRICK.

SPECIFICATION forming part of Letters Patent No. 584,293, dated June 8,1897. Application filed July 29, 1896. Serial No. 600,973. (No model.)

. lowing is a specification.

This invention relates to brick-making, and particularly to a brick; andthe object of the invention is to provide a brick of such peculiar andnovel construction that no mortar is required in joining the same.

A further object of the invention is to provide a brick having upon allsides and ends means for joining it to other bricks without employingmortar, cement, or other adhesive material.

The invention consists in the peculiar and novel construction of thebrick, and resides, essentially, in the special arrangementthereon ofmeans for j oiningit to other bricks with-' out mortar or other adhesiveelements.

In the accompanying drawings, forming part of this application, Figure 1is a perspective View of several of my bricks joined together formingpart of a front Wall. Fig. 2 is a perspective view of my brick upon alarger scale, looking at the bottom and rear side. Fig. 3 is alongitudinal central section on the line w m, Fig. 2. Fig. at is across-section on the line y y, Fig. 2. Fig. 5 is a perspective view of amodified form of brick. Fig. 6 is a crosssection of an inner brick.

The same letters of reference denote the same parts throughout theseveral figures of the drawings.

The brick hereinafter to be fully'described is intended for walls instructures of various character, and while it has special reference tobuildings it may be found not only desirable but exceedingly beneficialwhen used in furnace-linings and furnace-walls where the heat is sogreat as to cause expansion and contraction of the lining or wall.

The front bricks A-that is, the bricks employed to form the front of thewall-have a horizontal shoulder a and vertical shoulder Z) upon one edgeand one end, which form grooves B by having the square edges of theadjoining brick placed hard against the shouldered portions of thebrick. This groove may be filled with material to form ornamentaldividing-lines between the bricks.

One end of the brick has a vertical angular groove 0 and the other endhas an angular tongue or projection D. The top of the brick has roundprojections E and directly opposite the same in the bottom of the brickare formed corresponding cavities F, and a like cavity G is formed inthe center of the rear face of the brick to receive aplug to whichlathing may be secured when only one course of bricks is employed in thewall.

The inner or rear bricks II have their top and bottom surfaces, ends,and one side constructed identical with that of the brick A,hereinbefore described, except the shoulders at and b are omitted andwith the addition of a round projection h opposite the cavity G in theside of the brick.

It will be observed that in building a wall of my improved brick everybrick in the wall except the front bricks are joined or bound togetherupon the top and bottom and upon each side by the projections andcavities, and the ends of each brick, including the front bricks, arejoined or bound together by the tongue-and-groove connectionhereinbefore described. Owing to this perfectly rigid con nectionbetween the bricks forming awall, it is impossible for the bricks to bemoved or become displaced by the settling of the wall or from thecontraction or expansion of the same.

Referring now to the modification shown in Fig. 5 one side of the brickhas a vertical groove I upon each side of the cavity f. Directlyopposite on the other side of the brick are corresponding tongues g.This construction provides an additional tie between the sides of thebricks, and it is obvious that each course of bricks is not only tiedwith the course above and below, but is firmly and securely bound withthe course upon each side.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. As an improved article of manufacture a brick provided withprojections upon its top and corresponding cavities upon its bottom, acavity upon one side, and a corresponding projection upon the otherside, a vertical tongue upon one end, and a corresponding verticalgroove upon the other end, substantially as set forth.

2. A brick having a vertical shoulder and a horizontal shoulder,projections upon its top, and corresponding cavities in its bottom, aVertical tongue upon one end, and a corresponding vertical groove uponthe other end, substantially as set forth.

3. An outside brick having projections upon its top, correspondingcavities upon its hottom, a cavity upon the inner side adapted toreceive a corresponding projection of an inside brick, a vertical tongueupon one end, and

a corresponding groove upon the other end. I 5 In Witness whereof Ihereunto set my hand in the presence of two Witnesses.
